NEEDLE-THREADING DEVICE.

SPEGEFZOATION forming part of Letters Patent No. 694,984, dated March 11, 1902.

Application filed May 29, 1901.

To ctZZ whom it may concern.-

Be it known that I, ALFRED OLSON, a citizen of the United States, and a resident of San Diego, county of San Diego, and State of California, have invented certain new and useful Improvements in Needle Threading and Thread-Outtin g Devices, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate corresponding parts.

This invention relates to an improved needle-threading and thread-cutting device, the object thereof, being to provide an article of this character which is adapted for attac ment to a spool of thread,whereby it is always in position ready for use, and which is positive in action and has its knife-edge so arranged as to prevent accidental injury to itself or to the person using it.

The device is simple in construction, inexpensive, and durable, and it can be attached to a spool of any ordinary size. 7

The invention will be hereinafter fully described, and specifically set forth in the annexed claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of my improved device; Fig. 2, a vertical sectional elevation thereof looking in the direction of the arrow 1, and Fig. 8 a side elevation showing the device attached to a spool in connection with a spool-holder of a sewing-machine. These several views are drawn on an enlarged scale in order to clearly illustrate the parts; but it is obvious that the device will be made much smaller in practice.

In the construction of my invention as illustrated by the drawings I employ, primarily, a metallic tapering plug A,which is preferably square in transverse section,but which could be made triangular or octagonal, if desired. Leading vertically through the plug A, from the upper end thereof to a point approximating half its length, is a cylindrical opening a, which preferably has a tapering mouth a, to receive the needle, as 2, Fig. 1 of the drawings.

ing the thread and which has tapering mouths a so that the end of the thread can readily be inserted from either side.

As a means for connecting the device to a spool sharp-edged ribs of are formed on the lower end of the plug A, which cut into the spool and securely connect the device, as shown by Fig. 3 of the drawings.

The knife for cutting the thread embodies a plate B, which is of a contour equaling one side of the plug A and has a forked lower end to embrace one of the ribs a This plate may be secured to the plug A by a screw orany other suitable means; but I prefer to form a lug A on the plug A, extend it through an opening I) of the plate B, and rivet its outer end, whereby a secure and inexpensive means for fastening the said plate is provided. The upper end of the'plug A is provided with an inclined surface, which is adapted for guiding'the thread to be out, and this surface is parallel with one edge of the cutter, which is formed by the recess B in the plate B, the edge of this said recess being sharpened to effectually out the thread. By this arrangement of the cutter it will be noted that the knife-edge thereof being recessed is effectuallyprotected from accidental injury, and it is also so located as to prevent users of the device from accidentally cutting their fingers.

. In order that the device may be used in connection with a spool used on a sewing-machine, the lower end of the plug A is provided with a recess A to accommodate the spindle of the spool-holder, as shown by Fig. 3 of the drawings.

As the operation of preparing a needle for sewing by threading it from a continuous thread on a spool would not be complete until the thread was severed, this device is adapted to complete the whole operation by both threading the needle and severing the thread in one continuous operation. To this end a needle is placed within the opening a,

with its eye registering with the channel a 95 Then a thread, as 3, can be readily passed through without the necessity of any strain on the eyes ofthe user. Having threaded the needle, it is simply necessary to pull it outwardly, carryingthe thread with it. Then :00

by passing the thread within the recess IS, as shown by Fig. 3 of the drawings, it can be readily severed by a sharp pull.

In the foregoing description I have set forth the preferred form of my invention; but I do not limit myself thereto, as I believe that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

I-Iavingthns described myinvention, what I claim as new, and desire to secure by Letters Patent, is

The plug A, formed with the slanting top A the needle-holder a, having flared month a, the cross-channel a having flared months a the recess A", and the ribs a, adapted to engage the surface of the bore of a spool, to afford facility for holding said plng', all substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 6th day of May, 1901.

ALFRED OLSON.
